"I bought this to drill some wall tiles to fit a shower screen for a customer, complete waste of my time and money I expected better from Bosch Do not waste your money on this rubbish as already stated in the reviews this is a diamond sharpened bit NOT a diamond tipped bit very misleading"

"I bought this drill bit to drill into wall tiles. It was so bad I even had to check it was in the drill the right way round! It didn't cut into the tile at all. Suggest the DeWalt item sold by Screwfix (diamond head) which does however cut my tiles. I only wish Screwfix would listen to these reviews and either remove the item from sale or the shop assistant could advise me how I'd be waisting my money to buy this."

"I bought one of these bits to drill porcelain wall tiles, as it was described as suited for that purpose.It was totally useless, nowhere near as good as a standard masonry bit which took about half an hour!If you need to drill hard tiles, don't even consider this product, get a diamond core bit, I drilled 6 holes in five mins with one, using a constant dribble of water to cool it."
